Q2. Why is the apparent E-modulus determined from the slope of the unloading curve decreasing?
With increasing composite strain the apparent E-modulus determined from the slope of the unloading curve decreases, possibly because of strain induced damage of the brittle phase.
Q3. How much stress is released in the composite E-modulus?
2. The stress has been partly released every 0.02% in order to measure the apparent composite E-modulus as a function of1051-8223/$25.00 © 2009 IEEEaxial composite strain.
Q4. What is the axial stress of the Nb-Ta tubes?
The axial tensile stress of the Nb-Ta tubes develops during the cold working of the strand as a result of the plastic mismatch of Nb-Ta tubes and the Cu matrix [6].
Q5. What are the lattice parameters measured at RT?
The Nb-Ta and lattice constants measured in the extracted tubes are 3.3009 and 5.2886 , respectivelyTABLE The authorLATTICE PARAMETERS MEASURED AT RT FOR THE DIFFERENT PHASES IN THE STRAND MOUNTED ON THE CRITICAL CURRENT MEASUREMENT BARREL.
